Detailsinfo

A vulnerability was found in Netgear RAX30 (Wireless LAN Software) (the affected version unknown). It has been classified as critical. Affected is the function soap_serverd. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

NETGEAR RAX30 soap_serverd Stack-based Buffer Overflow Authentication Bypass Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR RAX30 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the soap_serverd binary. When parsing SOAP message headers, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-19839.
